Windows Phone 7 arrives in UK shops tomorrow

Orange will be offering the HTC 7 Mozart and the Samsung Omnia 7 - the latter shared with T-Mobile and Three. Vodafone has the HTC 7 Trophy, and O2 the HTC 7 HD.

O2's HTC 7 HD

Orange is trying to tempt buyers at its 155 Oxford Street store with a free Bluetooth headset if they buy one of its WinPho 7 handsets.

The carrier didn't mention that it will also be offering the LG Optimus 7 - so that's clearly not out on the big day.

Three will begin selling the Omnia 7 tomorrow on its The One Plan for £40 a month, on its Internet Texter 900 tariff for £38 a month, and on its Internet Texter 500 plan for £35 per month.

Samusung Omnia 7 will be available free from T-Mobile too, on plans starting at £35 a month - on a 24-month contract which will include 900 minutes, 500 texts and unlimited internet.

Orange's version will also be free to anyone taking out a £40-per-month, two-year contract. The package includes 1200 any-network call minutes, unlimited text, unlimited email, sat nav with Orange Maps as well as inclusive anytime internet browsing, Orange said.

The Mozart will also be free, if you sign up for a two-year, £35-a-month plan that includes 600 any-network call minutes, unlimited text, unlimited email, sat nav with Orange Maps as well as inclusive anytime internet browsing.

O2 said the HTC 7 HD will be available on its range of pay monthly smartphone tariffs, all of which come with unlimited Wi-Fi. The HD is free on a £40 two-year tariff that comes with 900 minutes, unlimited texts and 750MB UK data. The phone will also be available on O2’s PAYG tariffs for £379.
